ABOUT OUR TRUNKS
WHO ARE KRAKATOA TRUNKS PERFECT FOR?
The Krakatoa Pinatubo Trunks with a horizontal fly are perfect for active guys that prefer a little less leg length than our Boxer Briefs but aren't quite into Briefs, or for those of us that wish we were more active and equally enjoy the feeling of supportive, barely there, ultra-soft underwear. The horizontal fly provides easy reach, for single hand operation.
Whether you're working out or just lounging around the house, these Trunks will materially change your life.
WHAT MAKES THEM KRAKATOA?
- Feel softness like never before with an ultra-premium, hand selected 95% MicroModal fabric. We source only the best MicroModal because comfort is our #1 goal. (Learn about MicroModal). We then blend the MicroModal with 5% Spandex to allow for it to move with you.
- Enjoy more room with a large front pouch that provides space and support for your cargo, with complete separation from your thighs. No need to adjust anymore.
- Feel comfortable all day with a waistband that doesn't flip or fold.
- And keep them longer with the peace of mind of our 52 Wash Guarantee.
WHAT'S GREAT FOR THE WEARER?
The Krakatoa Trunks are specifically designed for maximum comfort. They work well for a variety of activities, from working out to lounging around, they can take on anything you throw at them. Once you make the decision to embrace this everyday luxury for your privates, getting dressed in the morning will never be the same again.
Great for: Walking, Hiking, Lifting, Exercising, Yoga, Lounging.
HEY ALEX, I HAVE QUESTIONS!
What should I know about the fit?
The Pinatubo Trunk is designed with a 2" inseam. The legs are designed to stay put, but can ride up a little depending on activities. The pouch is designed to be large enough to provide you room, with a Horizontal Fly for one handed quick draw action, while being double layered to also provide support and privacy for your privates. All of this is benefited by our use of MicroModal which is incredibly lightweight and breathable.
What if I'm in between sizes?
Our sizes run pretty true and the materials do have stretch to them.
But if you're not sure which size is going to be the best for you, consider these three things:- Your waist in inches (pants size is OK).
- If your legs touch at the thighs.
- If you have a small, normal or large butt.
If your legs touch and your butt is large, you might jump a size.
If you have a small butt and thin legs, you can downsize.
What's MicroModal fabric?
In a word. Soft.
Really soft, our MicroModal is hand-selected to be of the highest grade available.
MicroModal is a modern technical fabric that is manufactured with cellulose from renewable Beechwood trees. Compared with Cotton, it's odor-resistant, 3 times softer, 50% more breathable, and it's not nearly as polluting or water-wasting.
Why such a big pouch?
Men come in all different shapes and sizes but for years underwear failed to respect our anatomy.
Our pouch is designed for the majority of men out there to accommodate and coddle. It's a blend of being soft with some stretch where needed, but also supportive for all day comfort. You won't need to adjust yourself anymore, because sticking to your legs is a thing of the past.
When will my item ship? How long will it take to arrive?
Please allow 2-4 days for processing, and the usual shipping times from the USPS or UPS: inside the US you can expect to see your package between 3-6 days.
We'll send you a confirmation email with your tracking information as soon as it ships.
If you have any questions or don't receive an email, feel free to reach out via our Contact Us Page.
What is your returns and refunds policy?
Our number one goal is that you're happy with your purchase.
If something doesn't fit right on your regular priced Krakatoa, let us know and we will make it right.
Try on a pair and make sure it's perfect in you. If it doesn't work for you, your first regular priced pair is covered.
After this first pair, all underwear must be unworn, unwashed, in the original condition and packaging that you received them for a refund.
If you bought multiple pairs, make sure you try ONLY ONE PAIR for fitting before you decide to use the rest.
INTRO PAIRS ARE FINAL SALE AND NOT RETURNABLE.
How do I wash my Krakatoa?
Krakatoa is quite resistant to shrinking and fading, but machine-washing them in cold water using the delicate setting and drying in low heat will keep them looking fresher for longer.
Please do not bleach, iron, or dry clean your boxer briefs or trunks. You can also wash it by hand and lay it flat to dry, for great results.
What's your 52 Wash Guarantee?
We've built a tough product with reinforced stitching that lays flat and the very best materials we could get our hands on.
That said, you should follow the care instructions.
We provide a 52 Wash Guarantee which is triggered by either 52 washes or 12 months from the date of purchase. If your item has any structural damage before 52 washes or 12 months, we'll replace them for free.
A FABRIC TO OVERLOAD THE SENSES
Your skin never felt a fabric so soft and welcoming before. Three times softer than cotton, our high-grade, environmentally-conscious MicroModal fabric will make you rethink cotton and synthetics forever.
A POUCH FOR ALL OF US
Large, round, and deep support, without uncomfortable lift. Naturally odor resistant, it separates and cradles you, so you won't need to adjust anymore. Its double-panel construction keeps your privates more private.
A WAISTBAND THAT IS PURE LUXURY
Smooth and soft to the touch, the unflippable waistband won't mark your skin and keep you comfortable all day. To complement the art outside the waistband, its interior has positive affirmations to get you going at every break.

Very soft and comfortable. Horizontal fly is great. Will definitely be buying more if I can find a sale.
- Colin C.Verified Buyer2 days agoReviewingPinatubo Intro Trunk w/ Fly - $10Rated 5 out of 5 starsBest of bunch!
Interesting how marketing works when you start shopping for underwear you see nothing but underwear ads with introductory offers. Well I decided to try 4 different brands and the one pair I look forward to wearing is Krakatoa! The others are ok but these are the ones I wish I had everyday. They are soft comfortable and just right for support! Love the color to!

I have tried many different pairs of underwear and these are by far the best. I own every color. They fit amazing, they are cool, and the band doesn't pinch or roll down. Highly recommend.
